Won't show all Comm ports?

Ok....MM worked for quite a while. Then I got a Bluetooth GPS and the GPS Comm port went from 3 to 15. No biggie, I just went to MM config and told it to auto detect. Now, I open into MM and see there are no sats. So, I click on the bottom right sat icon and it says GPS not found. I go to GPS settings and I see the only comm port listed is 1. What gives? If I click Find GPS it says it cannot be found. I have no idea, and I use this thing everyday...PLEASE HELP....thanks, B
